Wow!! what a game. This has so many twists it keeps you locked in and playing until the early hours! The main plot line is good, and there are so many side plots I have lost count - I am still finding them. The add-ons are good too, and have been inter-laced with the original game well.
I am playing the game at full graphics and have had no problems that others have mentioned. Very addictive. I only hope more add-ons are made to keep us hooked even longer.
